British Lawmaker Jo Cox Has Died After Being Stabbed, Shot (UPDATED)

A female member of the British Parliament was airlifted to a hospital today after an attack by an unknown assailant left her in grave condition.

Jo Cox, a member of the Labour Party, was holding a town-hall meeting in Birstall near Leeds when a fight began outside the local library at around 1 P.M. local time. While the precise details of the skirmish are not yet known, the BBC reports that Cox was left bleeding at the scene after being stabbed and shot twice with what looked like a “handmade” firearm.

“There was a guy who was being very brave and another guy with a white baseball cap who he was trying to control and the man in the baseball cap suddenly pulled a gun from his bag,” said witness Hithem Ben Abdullah. The Guardian reported that Abdullah went on to say that the MP got close to a scuffle between two men, and one of them brought the gun out.

Police say that a 52-year-old male has been arrested “in the area,” and an investigation is under way regarding the incident. Another person was also reportedly injured at the scene, though the extent of their injuries are unclear.

Cox was taken to Leeds General hospital, where she is being guarded as she undergoes intensive care.

The BBC has been circulating this picture as the moment the suspect was arrested.

This story is developing, and we shall add more details as they become available.

UPDATE: 10:40 AM EST: While it is not yet clear that this was the motivation for the fight, NBC News noted that the incident occurred amid discussions on Brexit. Cox is in favor of keeping the UK a part of the European Union, and the Stronger In campaign tweeted that they would suspended activities due to the attack.

We are suspending all campaigning for the day. Our thoughts are with Jo Cox and her family.

Footage of the suspect’s arrest earlier today has also surfaced, courtesy of Daily Mirror.

The Mirror also reported that several eyewitnesses at the scene said the attacker yelled “Britain first,” during the incident, which means that Cox’s death may, in fact, be due to her stance of keeping the UK in the EU.
